Abstract

An apparatus and method for gesture recognition in a portable terminal. An operation of the portable terminal includes determining a user situation by using at least one situation information, determining a user'"'"'s gesture by using at least one sensor measurement value, and performing a function corresponding to the user situation and the gesture.

Claims

1. A method of operating a portable terminal, the method comprising:

determining a user situation by using at least one situation information;

determining a user'"'"'s gesture by using at least one sensor measurement value; and

performing a function corresponding to the user situation and the gesture.

2. The method of claim 1, wherein the at least one situation information includes at least one of user location data, a current time, a frequently used application, a user'"'"'s call/communication history, a Short Message Service (SMS) usage history, and a Social Network Service (SNS) usage history.

3. The method of claim 1, wherein the user situation includes at least one of a current user location, information on whether the user is located in a Point Of Interest (POI), a POI class, information on whether the user is moving or stationary, a list of application most frequently used at a current time zone, and a communication means most frequently used at the current time zone.

4. The method of claim 1, wherein the at least one sensor measurement value includes a least one of an accelerator sensor measurement value, an earth'"'"'s magnetic sensor measurement value, a pressure sensor measurement value, and an angular velocity measurement value.

5. The method of claim 1, further comprising:

before the determining of the user situation, determining whether to enter a gesture recognition mode.

6. The method of claim 5, wherein whether to enter the gesture recognition mode is determined according to whether a key predefined to report a start of a gesture period is input.

7. The method of claim 5, wherein whether to enter the gesture recognition mode is determined according to whether a start gesture predefined to report a start of a gesture period occurs to report a start of a gesture period.

8. The method of claim 1, wherein the performing of the function corresponding to the user situation and the gesture comprises searching a table to find a function corresponding to the user situation and the gesture.

10. The method of claim 1, further comprising:

after determining the user situation, displaying at least one function icon corresponding to at least one gesture usable in the determined user situation.

9. The method of claim 9, wherein the table includes at least one of a gesture list, user situation lists that are dependent on respective gestures, a function list corresponding to a combination between the gesture and user situation a user situation list, function lists that are dependent on respective user situations, and a gesture list corresponding to a combination between the user situation and the function.

11. A portable terminal apparatus having a controller for controlling a function of the portable terminal, the controller comprising:

a situation recognition unit configured to determine a user situation by using at least one situation information;

a gesture determining unit configured to determine a user'"'"'s gesture by using at least one sensor measurement value; and

a function execution unit configured to perform a function corresponding to the user situation and the gesture.

12. The apparatus of claim 11, wherein the at least one situation information includes at least one of user location data, a current time, a frequently used application, a user'"'"'s call/communication history, a Short Message Service (SMS) usage history, and a Social Network Service (SNS) usage history.

13. The apparatus of claim 11, wherein the user situation includes at least one of a current user location, information on whether the user is located in a Point Of Interest (POI), a POI class, information on whether the user is moving or stationary, a list of application most frequently used at a current time zone, and a communication means most frequently used at the current time zone.

14. The apparatus of claim 11, wherein the at least one sensor measurement value includes a least one of an accelerator sensor measurement value, an earth'"'"'s magnetic sensor measurement value, a pressure sensor measurement value, and an angular velocity measurement value.

15. The apparatus of claim 11, wherein the controller determines whether to enter a gesture recognition mode before determining the user situation.

16. The apparatus of claim 15, wherein whether to enter the gesture recognition mode is determined according to whether a key predefined to report a start of a gesture period is input.

17. The apparatus of claim 15, wherein whether to enter the gesture recognition mode is determined according to whether a start gesture predefined to report a start of a gesture period occurs to report a start of a gesture period.

18. The apparatus of claim 11, wherein the function execution unit searches a table to find a function corresponding to the user situation and the gesture.

19. The apparatus of claim 18, wherein the table includes at least one of a gesture list, user situation lists that are dependent on respective gestures, a function list corresponding to a combination between the gesture and user situation, a user situation list, function lists that are dependent on respective user situations, and a gesture list corresponding to a combination between the user situation and the function.

20. The apparatus of claim 11, further comprising a display means for displaying at least one function icon corresponding to at least one gesture usable in the determined user situation after determining of the user situation.
